Airtac PSB Single Acting Compact Cylinder PSB12X10SR
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB12X10SR is a single acting, push type (spring return) pen-size mini cylinder with a Ø12mm bore and 10mm stroke. A single air port drives the push stroke; the built-in return spring resets the rod when air is released, so only one solenoid line is needed.

About the Airtac PSB Single Acting Compact Cylinder PSB12X10SR
The AirTAC PSB12X10SR is a JIS pen-size single-acting push cylinder with a 12mm bore and 10mm stroke. Air entering the single M5x0.8 port extends the Ø5mm rod, while an internal spring retracts it upon exhaust. This fail-safe design ensures the rod returns home if air pressure drops, making it ideal for clamp-release and ejection tasks. It supplies 42.9 N of net push at 0.5 MPa.
Built with a SUS304 stainless barrel and rod, this slim actuator fits tight jigs and light end-of-arm tooling. The built-in magnet (-S) supports reed or electronic switches for position sensing. A fixed TPU bumper cushions the stroke ends, and the R axial inlet keeps plumbing inline. Plan for a safe working load of about 26 N (roughly 60 percent of the 0.5 MPa rating) to account for seal friction.
Airtac PSB Single Acting Compact Cylinder PSB12X10SR Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB12X10SR |
|---|---|
| Series | PSB JIS pen-size mini cylinder |
| Bore size | Ø12 mm |
| Rod diameter | Ø5 mm |
| Stroke | 10 mm |
| Acting type | Single acting, push type (spring return) |
| Port size | M5×0.8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.2 – 0.7 MPa |
| Proof pressure | 1.2 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 50 – 800 mm/s |
| Return | Return spring (push by air) |
| Max standard stroke | Up to 60 mm |
The spring holds the rod retracted; applying air pushes the rod out, and removing air lets the spring return it. Forces below are the NET spring-deducted values from the AirTAC thrust table. Confirm against the product label before installation.
Net Push Force (Ø12mm)
| Pressure | Net push force |
|---|---|
| 0.5 MPa | 42.9 N |
| 0.7 MPa (max) | 65.5 N |
These are the usable push forces after the return spring is subtracted, taken directly from the AirTAC single-acting thrust table. Minimum operating pressure is set by the spring, so this model needs at least the lower pressure shown to move.

Where the Airtac PSB Single Acting Compact Cylinder PSB12X10SR Is Used
Part Ejection
Pushes finished metal parts out of a CNC machining fixture. The spring-return design guarantees the ejector clears the work area when air is shut off.
Gate Diverter
Acts as a sorting gate on a packaging line. The compact stainless body handles damp washdown environments while the single air line simplifies tubing.
Clamp Release
Secures cardboard cartons during a sealing process. Fail-safe retraction releases the clamp automatically if the compressed air supply fails.
Is the Airtac PSB Single Acting Compact Cylinder PSB12X10SR the Right Cylinder?
This 12mm bore provides 42.9 N net push at 0.5 MPa and 65.5 N at 0.7 MPa. If you need less force, the Ø10 bore offers 29.8 N at 0.5 MPa; for heavier tasks, the Ø16 bore yields 74.8 N. The internal spring requires a minimum 0.2 MPa before motion begins. Because the rod is only Ø5 mm, use an external guide for off-axis loads to prevent bending.
When ordering, confirm the 12mm bore, 10mm stroke, S magnet for sensing, R axial back cover, and your mounting bracket. The fixed TPU bumper handles light impacts, but meter-out the exhaust if moving heavy tooling mass at higher speeds.
Quick checklist
- ✓ Net push force at your working pressure
- ✓ Only one air line / solenoid needed
- ✓ Fail-safe retract on air loss
- ✓ Magnet (S) for sensors?
- ✓ Stroke ≤ 60 mm (single-acting limit)
- ✓ Keep the load coaxial — avoid side load
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.2 – 0.7 MPa operating pressure.
- check Allow for spring force in the stroke direction.
- check Do not add an external return mechanism.
- check Keep the load coaxial; avoid side load on the thin rod.
- check Do not dismantle the front or back cover.
Airtac PSB Single Acting Compact Cylinder PSB12X10SR FAQ
The net push force is 42.9 N at 0.5 MPa and 65.5 N at 0.7 MPa (maximum pressure). Because an internal spring opposes the air stroke, a minimum of 0.2 MPa is required before the rod extends. The spring automatically retracts the rod on air loss.
Yes, the S suffix indicates a built-in piston magnet compatible with AirTAC reed or electronic solid-state switches. The cylinder uses a fixed TPU bumper at each end to decelerate the last few millimeters of travel, but you should meter-out the exhaust or add an external shock absorber for heavy tooling mass at high speeds.
